There are 20 poles with a constant distance between each pole A car takes 24 second to reach the 12th pole. How much will it take to reach the last pole

One Answer on this Question

1. Let the distance between each pole be x m. Then, distance up to 12th pole = 11x m

   ∴ Speed = 11x22m/s

   ∴ Time to cover total distance up to 20th pole

   = 19x×2411x

   = 41.45 s
